Recommended Protocol

  1. Remove centrifuge tube from packaging.
  2. Re-suspend centrifuge tube contents in 10 mM Phosphate buffer pH 7.2 so that the final volume is 100 uL. This will yield a 10 mg/mL solution of GlowDots.
  3. Filter re-suspended GlowDots using a 13 mm diameter PVDF filter with 0.22 µm pore size.
  4. Incubate cells with 0.3 mg/mL for 1 hour.
  5. Image cells on confocal microscope with appropriate excitation laser.
